The action of semicarbazide on the aggregation of the tropocollagen macromolecule [PDF]
Biochemical Journal, 1967 1. A difference in conformation was found between the collagen in solutions treated with semicarbazide hydrochloride and those treated with sodium chloride. This difference could be correlated with the difference in extent of aggregation between the fibrils precipitated from these solutions. 2.

ANTAGONISM OF THE SPINAL ACTION OF DIAZEPAM BY SEMICARBAZIDE [PDF]
British Journal of Pharmacology, 1974 In spinal unanaesthetized cats, pretreatment with semicarbazide (200 mg/kg) 2–4.5 h prior to the administration of diazepam (1–4 mg/kg) completely blocked the enhancement of the segmental dorsal root reflex by the latter compound. Pyridoxine hydrochloride (200 mg/kg), given 3.5 h after semicarbazide, restored the spinal effect of diazepam administered ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis
The Chemical Record, EarlyView.Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
